After attempting to subscribe to this blog via e-mail using the FeedBurner widget for this purpose, I have discovered that the supplied audio CAPTCHA appears to be broken. No matter how many times I listen to and enter the numbers, I am unable to complete the subscription process! A message has already been sent to concerning this serious problem. I urge all of you to do likewise. Let’s get as much visibility to this issue as possible so the FeedBurner folks will fix it right away!

Update: A FeedBurner support representative tells me that the problem appears with both the audio and visual CAPTCHA. It involves a timeout issue with certain browser and Internet service provider combinations. While it works fine with Internet Explorer 7.0 for one user, it works only with Firefox 2.0 for another. Those encountering this ongoing inability to complete e-mail subscriptions should include their browser version and the name of their Internet service provider in messages to the support team.
